The Clarke Error Grid (CEG) analysis showed that 81.7% of the readings appeared in the grid's A zone with the remaining 18.3% percent falling in the B zone. The grid's A zone represents results that are the most clinically accurate and results in the B zone are considered clinically acceptable.

The Continuous Glucose-Error Grid analysis (CG-EGA) showed that 99.6% of the readings were clinically accurate (A) and 0.0% were benign (B) errors with a combined A+B of 99.6%.

94.4% of the calculated CGM rates were within +/-1 mg/dL/min of the reference rate and 99.6% were within +/-2 mg/dL/min.

"We value this opportunity for engagement with the critical care community to share this Symphony study data with key opinion leaders in the field as we prepare for upcoming European and FDA regulatory trials," said David Walton, Echo Therapeutics' Vice President of Marketing and Commercial Development. "As we explore collaboration opportunities, we are very encouraged by the increasing awareness of our developmental, non-invasive continuous glucose monitoring technology."
